Cloning, Characterization and Bacterial Expression of the Β-amyrin Synthase Gene from Panax Japonicus C. A. Mey
Panax japonicus C. A. Mey. is one of the rare traditional Chinese herbal medicines; its main active ingredient is ginsenosides. β-amyrin synthase (βAS) is the rate-limiting enzyme in the biosynthesis pathway of oleanane-type ginsenosides. We cloned for the first time the full-length cDNA of βAS from P. japonicus (GenBank: KP658156) using reverse transcription-polymerase chain reaction (RT-PCR) ...
متن کاملCloning and characterization of a β-amyrin synthase gene from the medicinal tree Aralia elata (Araliaceae).
Aralia elata is an important medicinal plant in China; it produces large amounts of oleanane type triterpene saponins. A full-length cDNA encoding β-amyrin synthase (designated as AeAS) was isolated from young leaves of A. elata by reverse transcription-PCR. The full-length cDNA of AeAS was found to have a 2292-bp open reading frame, encoding a protein with 763 amino acid residues. The ded...

در طی چند دهه ی اخیر، مفهوم «تراژدی» و «قهرمان تراژدی» توجهی روزافرون را تقریباً در تمام حوزه های نقد ادبی به خود معطوف کرده است. برخی نظیر ارسطو، نیچه، و آرتور میلر به بازخوانی آن پرداخته و برخی دیگر نظیر سارتر، استریندبرگ، یوجین اُنیل، برتولت برشت، و آنتونین آرتود به افزودن ابعاد نوینی به این مبحث همت گماشته اند. آنچه قهرمان تراژدی مدرن را از مفهوم کلاسیک آن متمایز می کند نه لغزش تراژیک متداول ...
Transformation and expression of Penicillium funicolusum glucose oxidase gene in yeast
Glucose oxidase is an important enzyme hydrolyzing for its hydrolyzing activity on glucos. It possesses and has a wide board of applications in different industries such as bakery, pharmaceutical, plant pathology and biosensors. In this study, yeast (Saccharomyces cerevisiae) was transformed successfully by the glucose oxidase gene (gox) obtained from Penicillium funicolusum. The secreted gluco...
متن کاملFunctional Characterization of CYP716 Family P450 Enzymes in Triterpenoid Biosynthesis in Tomato
Triterpenoids are a group of structurally diverse specialized metabolites that frequently show useful bioactivities. These chemicals are biosynthesized from the common precursor 2,3-oxidosqualene in plants. The carbon skeletons produced by oxidosqualene cyclase (OSC) are usually modified by cytochrome P450 monooxygenases (P450s) and UDP-dependent glycosyltransferases. These biosynthetic enzymes...
